I booked an Audi A4 but was given an Audi Q2. The same thing happened during my last car rental in Rome: I booked an SUV and got an Audi A4. The trunk could only fit two 26-inch suitcases by folding down one of the rear seats, but fortunately, there was only one passenger in the back. The diesel car did save me about 15% on fuel, but its condition was terrible—the right rear door was dented, the right rear fender was detached, and there were scratches all over the vehicle. Parking it anywhere could make it look like it had been in a collision. At return, the car rental staff just did a quick check and cleared it. During the rental process, the staff was very polite. I guess this rental company will be my only choice when renting cars in Europe in the future.
